1. An image processing device, for performing a filtering operation on image data according to a set of filter data, the device comprising:
a data reconstruction circuit, reconstructing data of a plurality of blocks in the image data to generate first reconstruction data, and reconstructing the set of filter data to generate second reconstruction data;
a memory, storing the first reconstruction data and the second reconstruction data; and
an intelligent processor, executing a depthwise convolution operation according to the first reconstruction data and the second reconstruction data to generate feature map data;
wherein, two adjacent among the blocks have partially same data, and quantities of columns of the second reconstruction data are associated with a channel count of the depthwise convolution operation.
